Without breakfast, all of us ­ irrespective of age ­ are likely to experience the late morning slump; tiredness, sleepiness and the urge to sit back. Our efficiency goes down further as the day progresses.Moreover, skipping the first meal of the day leads to intense hunger pangs by late morning and we end up eating chips, samosas, burgers or other high­ fat unhealthy foods. Break fast­skippers are more likely to be overweight. A good breakfast leads to a more active, productive day. Research has found a definite connection between skipping breakfast and memory impairment in both young and older adults. Moreover, breakfast is directly linked with performance in school and college. Breakfast should contribute at least one ­fourth of our daily requirement of nutrients. An ideal breakfast should contain adequate amounts of carbohydrates, proteins and fats in addition to minerals and vitamins. Essentially this means including most of our food groups in the morning meal. Whole grain cereals ­ like atta in parathas and puris, dalia, suji, etc. are an integral part of the traditional Indian breakfast. Their high fibre and protein content provides a feeling of satisfaction, which lowers the urge to snack before lunch. On the other hand, high­ sugar foods actually make people sleepier, not active.

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea­bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.

Sedimentary rocks leads to the formation of oil deposits because
